ABSTRACT:
An electronic camera includes an image-capturing element that captures a subject image and outputs image-capturing signals each corresponding to a pixel; and a control device that executes gradation correction on the image-capturing signals output by the image-capturing element. In the electronic camera, the image-capturing element is split into a plurality of pixel areas each containing a plurality of pixels; and the control device calculates average values of image-capturing signal values in the pixel areas, which are output by the image-capturing element prior to a shutter release, determines an exposure quantity and gradation characteristics based upon the average values having been calculated each in correspondence to one of the plurality of pixel areas, engages the image-capturing element to capture an image at the exposure quantity having been determined in response to the shutter release and executes gradation correction on image-capturing signals output by the image-capturing element in conformance to the gradation characteristics having been determined.
